How does a diesel generator work?

Diesel generator by Deutz

DEUTZ Diesel generators combine a powerful and reliable source of electricity with great fuel economy.

Our diesel generators are ideal for farms, homes, businesses, utilities, governments, and emergency services that are off-grid or need emergency or supplementary power.

Designed for our region’s unique conditions, world-class DEUTZ Power Solutions use the best available design, technology, and parts.

What is a diesel generator?

A diesel Genset, or diesel generator set, combines an internal combustion engine and an electrical generator (alternator) mounted together to form a single piece of equipment.

The electromechanical machine produces an AC electrical current from the thermal energy of combustion through a double-cascade converter.

This involves thermal energy introduced by diesel fuel being converted to mechanical energy as the engine rotates, and the mechanical energy becoming electric energy.

Diesel generator operating modes include:

  • Island mode, where the Genset is the sole source of energy for the user system. Examples include self-powered and work site equipment.
  • Backup power when the existing network fails or is not operating. Gensets can activate automatically to ensure hospitals, computers and industry keep operating.  
  • Parallel mode, where multiple units work together to ensure power continuity if one fails, the required load is too big for one Genset, or more power is needed at peak times.
